In terms of regular care, plan to water your areca palm whenever the soil starts to dry out. To keep outdoor palms healthy, its especially important to keep them hydrated during hot and dry weather conditions. Indoor palms often don’t receive enough light unless they are placed near a very bright window. So, it can benefit your palm to bring it outdoors in warm weather to be exposed to diffused sunlight. Feed indoor and outdoor palms throughout the growing season. These palms don’t need much in the way of pruning or trimming. Wait to remove any dying fronds until they are mostly brown, as they still can play a role in photosynthesis.
Light
Outdoors, these plants like bright, filtered sunlight, but they also can tolerate full sun. Indoors, areca palms do best with bright light exposure from a south- or west-facing window.
Soil
For potted indoor plants, a well-draining, peat-based potting mix is perfect. Outdoor specimens do best with a rich, slightly acidic soil that has very good drainage. Amending with sand and peat moss might be necessary to improve porousness and lower soil pH.
Water
Like many palms, areca palms like moist soil, but they are sensitive to overwatering and cannot tolerate being waterlogged or sitting in a water-saturated potting mix. So let the soil or potting mix dry out slightly between waterings. Areca palms also are sensitive to fluoridated water, so use distilled water or collected rainwater.
Temperature and Humidity
Indoors or outdoors, this plant does best in average temperatures of 65 to 75 degrees Fahrenheit. It will do fine planted in the garden in regions where outdoor temperatures don’t dip below about 50 degrees Fahrenheit. When grown as an indoor plant, keep the plant away from cold windows, air conditioners, and heat sources. And if you place potted plants outdoors during the summer, be sure to bring them in before temperatures dip below 50 degrees Fahrenheit. Sudden cold bursts can cause dark spots to form on the leaves. High humidity is essential to keeping an areca palm looking its best. The plant will acclimate to normal indoor humidity. But if the air is too dry, it is common for the leaf tips to turn brown.
Fertilizer
The areca palm is a heavy feeder and requires fertilizing from spring to early fall with a liquid fertilizer, following label instructions. Do not feed it during the late fall and winter when the plant is dormant.
Propagating Areca Palm
You can propagate areca palm by root division, which will grow a lush plant faster than from seed, but you will not be successful doing so with cuttings. Root division can be done at any time during the year, but the plant will be its strongest in the spring. To divide by root division from a potted areca palm:
How to Grow Areca Palm From Seed
Areca palms can also be grown from seed. It is unusual to find areca palm seeds at garden centers; however, you can harvest seeds from the fruits that appear after the yellow flowers bloom. If you propagate with seeds, germinate them at home by planting them slightly covered in a seed-starting mix. The older, orange-colored seeds generally have a better germination rate than the newer, greener seeds. Germination takes about six weeks with soil temperature over 80 degrees Fahrenheit and relatively high humidity. Keep the seed-starting mix moist but not soggy as you wait for germination, and then continue to keep the seedlings moist as well. When the seedlings grow a few leaves, plant them outdoors ten feet apart, or plant three to four seedlings to a 12-inch pot to create a full look.
Potting and Repotting Areca Palms
Areca palms like a somewhat cramped container with ample drainage holes, and crowded roots will aid in keeping the palm’s size in check for growing as a houseplant. However, it’s still ideal to repot it every other year or so to refresh the potting mix and remove fertilizer salt deposits that have built up in the container. You can use the same pot if the palm’s root ball still comfortably fits. Otherwise, move up one container size. Replant the palm at the same depth as it was previously planted.
Common Pests & Plant Diseases
Areca palms don’t have serious issues with pests or diseases. Occasionally a palm be infected with lethal yellowing, an insect-transmitted bacterial disease that causes fronds and ultimately the whole palm to die. Outdoor palms are more likely to become afflicted with this, and because treatment usually isn’t effective, it’s typically best to remove the palm before the disease spreads. Indoor areca palms are vulnerable to common houseplant pests, including mites, aphids, mealybugs, scale, and whiteflies, which can cause foliage damage and discoloration. Treat any infestation as soon as possible.
Common Problems With Areca Palm
Although the plant can be easy to care for, it’s prone to one particular issue that happens to both indoor and outdoor areca palms: Keep an eye out for leaf tip burn.
Leaf Tip Burn
Leaf tip burn means the tips and leaves have turned yellow or brown. This can be caused by:
Chilled airOverwateringUnderwateringPoor soil conditionsCompacted roots
The areca palm is self-cleaning, which means it typically will shed its brown fronds on its own. For an indoor areca palm, it might be best to first amend the soil to make sure it’s draining well and the roots are not sitting in water. Or, move the pot to a spot with less light and higher humidity before thinking about the last resort of repotting the plant. You can also manually sheer off brown spots to tidy up an indoor or outdoor plant.
